Never complain and never explain.
Know or listen to those who know.
Problems are not stop signs, they are guidelines.
If you're going through hell, keep going.
You never know what motivates you.
Be gentle to all and stern with yourself.
The most effective way to do it, is to do it.
Begin to be now what you will be hereafter.
Go for it now. The future is promised to no one.
Expect problems and eat them for breakfast.
Without feeling abashed by my ignorance, I confess that I am absolutely unable to say. In the absence of an appearance of learning, my answer has at least one merit, that of perfect sincerity.
